Pec Butterfly
The Pec Butterfly from the STEEL series is a machine for isolated chest training. The arms move in an arc in front of the body, mimicking a dumbbell fly but with even resistance through the full range. Unlike presses, the triceps barely work, so the chest does all the work.
Nothing has to be selected — click an option again to clear it and we will recommend one. This choice applies to every machine in your request by default; mixing colours within one set is arranged individually. Any RAL shade on request, photos show the standard black frame.

Why choose the Pec Butterfly
Pure chest isolation: no help from the triceps, ideal for finishing after presses.
Forearm pads: the load goes through the forearms, so grip never limits the chest.
High back pad: a stable back and head position during the exercise.
Adjustable seat: keeps the shoulders at the right height relative to the arms.
Custom colours: a one- or two-colour frame and upholstery matched to your gym.
Who the Pec Butterfly is for
It belongs in the chest area of every gym. Beginners who find dumbbell flyes technically demanding will value it, as will advanced lifters who want to finish the chest without loading the elbows.
